srs'rnu or PAINTING.

Application filed August 29, 1921. Serial No. 496,570.

the operator may adjust the tank and its,

carried spray head vertically to paint the surface in vertical strips.

In a companion application, Serial No, 469,427, filed by me May 14, 1921, now patent;

No. 1,440,147 I have shown a construction designed for the same purpose as the one herein illustrated, but in which the guide ropes which serve to hold the tank and spray head the proper distance from the surface. to be ainted were free to move. In my present invention, these guide ropes have their weighted ends connected together and are spaced the proper distance by a skeleton frame from the surface to be painted. Also, my resent invention contemplates a peculiar orm of guyed anchor for the inner end of the boom whose guy ropes, preferably not less than three in number, are dsined to be anchored to the ground or secure to the edges of the tank, as the case may be.

The .boom in the present construction is also of novel form and contains a manipulative winding drum or air motor by which the paint tank can be raised orlowered .rel-

ative to the space tobe covered. The weighted ends of the guide ropes for the paint tank are connected together by a skeletonframe which also serves to space said wei lited ends the proper distance from the sur ace being covered. The guy ropes and guide ropes are preferably in the form of light twisted wirev cables and are mounted on sheaves" whereby they may be wound when desired so as to occupy but little space for transportation purposes and at the same time be in readiness for immediate use. By-making the parts light and portable they canv be installed in position by one man, but new ally three men constitute a crew. 2

I Figure 17 is a detail view of the form ofhook shown in Figure 16.

In the drawings, referring to Figure 1,

A indicates a boom anchoring tripod which form supporting legs for a platform plate 2.

l igatformplate provides a mount for a SWIVO ng rod 3, preferably having an eye 4 at its end, by which a rope or cable-may ranged parallel t3 each other and bent to be attached therein for-the purpose of securing one end of the'boomfin position,

Each leg of this anchoring tri 0d provides a mount for a sheave, pre erab y consisting of the side plates 5' and hub 6,

The hub casting 6 is provided with a se- I ries of perforations registering with perforations in plates for receivin a pin 7 adapted to pass through correspon 'ng openings in the legs 1, whereby each sheave may be locked in position. Each sheave has a fine wire cable or rope 9 mounted thereon and this cable carries a sna hook 10 at its outer. end (see Figure 14). si ed to be engaged with the swivel eye 13 of ii grab hook 14 (as shown in Figure 15) or 15 (as shown in Figures 16 and 17) and thus the wire cable 9 becomes a guy rope for the anchoring tripod.

Where the tank to be painted is not pro vided with an overhanging save, as is sometimes the case, after positioning the boom anchor at approximately the center of the tank, the cables 9 are dropped over the side edges, and after securing the ground anchors into the ground, snap hooks 10 are engaged with the swivel eyes of the ground anchors 15'. After this is done, the sheaves are rotated so as to take up any slack in the cables or guy ropes 9 and draw them taut, the in 7 being inserted to hold the sheaves 111100 ed position.

16 indicates the inner section of a boom having an eye 17 secured in its end (see Figure 9) by which the inner end of the boom may be connected by a rope 18 to the eye 4 of the swivelling anchor rod. Boom .channel member 25 under 16 is connected by a reducing coupling 19 to another boom section 20 in turn connected by a reducing coupling 21 to an outer and smaller boom section 22. All of these boom sections are referably in the form of hollow pipes and or purposes of transportation ma to ccupy, the least possible space.

On one of these boom sections is detachably secured a truck frame consisting of bars 23 and 24, said bars being connected to a .de ends of which are rollers'26. In this manner the outer end of the boom can' be moved around the ank the rollers 26 being supported by the of the tank.

27 indicates what may be designated as an icultural seat, detachably securedto one .o the boom sections and behind. a frame of bent members 28 and 29 on comgpeed whic are mounted a winding drum 30 and an 0 rating shaft 31, the latter being provid with crank handles 32 by which an operator seated in seat 27 may manipulate the windgnfidrum to pay out or take up a rope or e 33- passing over a sheave 94, mounted in the outer end of the boom and which rope or cable 33 supports a paint tank 35.

Thewin w n as m c n a 0 enter by manipulating this drum ma alowlyrauacrlowcrthepainttank. This is snap hook is debe nested or telescoped together so as system might be replaced by an air'motor. The outer end ofthe boom has a cross-arm 36 mounted thereon (see Figures 3 and 9 which cross-arm may be braced by a bar 3 The ends of this cross-arm are provided with brackets 38 provided with mounts for sheaves 39 which may be similar to the sheaves comprising the parts 5 and 6 heretofore referred to.

40 indicates a sheave guard arranged over the sheaves 39. Each sheave 39 carries a wire rope or cable 41 constituting guide ropes for the paint tank and each gmde rope is [provided with a weight 42 at its lower en ,,which weiglh may resemble-the well known sash weig t. Each weight 42 is provided with anopening to receive a s acing bar 43 which is held in position y set screws 44. The weights 42 may thus be ad justed toward or from each other.

45 indicates rods or pipes mounted in the lugs or cars 51 in which are plvotally mounted bolts 52 having butterfly nuts 53 on their upper ends. These bolts are desi ed to be received in recesses in the edges 0 a casting 54', which casting carries a spray head 5 a pressure gau 56, and a reducin valve 5 all of whic may be connected-and are utilized for the purposes described in the companion application.

By making the paint tank separable from the head casting carrying the above mentioned parts, it is possible to remove the tank from the apparatus and replenish 1t with a new supply of paint.

This head casting is provided with guiding arms 58 (Figures 2 and 3) havi openings 59 in their ends into which guide ropes 41 may be introduced from the side through the obli uely disposed slots 60.

A, In 0 ration, i the guy ropes 9 are to be seen to the ground anchors, such are employed. Or, if the grab hooks shown in Figures 15 and 16 are to be used, they are placed in position and the guy ropes drawn taut. The boom is now anchored to the swivel rod and the drum truck arranged in position. The weighted guide ropes 41 are paid out fromthe sheaves 39 on the cross arm of the boom, refer-ably with the lower ends of the weights 42 juat clearing the ground. One man occupies seat 27 and by signal raises or lowera the t tankace-M s of enr -lll made bymeans of a rope or cable which not only constitutes a flexible connection but one which can be let out or taken up to properly mount the boom on tanks of different diameters, and, of course within a certain range of diameters.

In view of the above, it will be seen that the several objects of the invention are 'achieved and other advantageous results attained.

As many changes could be made in carrying out the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim is: I
